Shenheng Power outlines dry type transformer standards for substations

Shenheng Power Equipment Co., Ltd. detailed technical standards for dry type transformers used in substation projects, emphasizing fire safety, compact installation and lower maintenance. The company said the products are aimed at indoor, space-constrained sites such as metro stations, hospitals, data centers and high-rise buildings.

Why it matters: - Dry type transformers are designed for substations where fire risk, space limits and environmental rules shape equipment choices. - The design can help reduce oil-related hazards, simplify installation and support indoor deployment near load centers. - The company positions the product for projects where reliability and footprint matter as much as initial cost.

What happened: - Shenheng Power Equipment Co., Ltd. outlined technical standards for its Professional Dry Type Transformer for Substation Project. - The company is based in Yueqing, Zhejiang Province, and was established in 2001. - Shenheng Power said the product is intended for indoor installation in commercial complexes, metro stations, data centers, hospitals and industrial zones. - More information is available in the company's announcement.

The details: - The SCB series includes 10 kV and 24 kV cast resin models. - The transformers use epoxy resin casting under vacuum conditions to seal the coils. - The sealed design is meant to reduce routine maintenance and improve resistance to moisture and dust. - The materials are engineered to be self-extinguishing in an external fire. - The oil-free design removes the risk of oil leakage into soil or groundwater. - The oil-free design also eliminates explosive pressure concerns tied to fluid containment. - The units do not require oil containment pits or fire-rated separation walls. - CHSH said the transformers can help place substations closer to load centers, which can cut cable requirements and transmission losses. - The units include integrated temperature control systems and forced air cooling options. - The cooling setup is designed to handle temporary overloads during peak demand. - Cast resin construction is meant to provide mechanical strength against short-circuit forces. - The maintenance profile relies mainly on visual inspections and dust removal. - The product portfolio ranges from 500 kVA to more than 3000 kVA. - The sealed structure is designed to resist corrosive atmospheres, salt spray and high humidity. - CHSH said the transformers are suited for coastal industrial parks and high-altitude sites. - The company serves as a supplier for the State Grid of China.

Between the lines: - The release reflects a broader shift toward indoor-friendly power equipment in dense urban infrastructure. - The emphasis on low maintenance and compact footprints suggests demand from sites that cannot easily support frequent service access or large civil works. - CHSH is also signaling that the transformer is part of a larger system offering, not a stand-alone product. - The mention of international industrial standards points to an effort to reassure buyers on quality control, though the release does not name specific certifications.

What's next: - CHSH said its R&D team works with project designers to match voltage taps, enclosure configurations and switchgear requirements. - The company will continue marketing the transformers for projects that need technical integration support across high- and low-voltage systems. - Buyers seeking specifications and product portfolios can review the company’s website for additional details.

The bottom line: - Shenheng Power is pitching dry type transformers as a safer, smaller-footprint option for substations where oil-filled equipment is harder to justify.
